Based on the characteristics of wireless network nodes and combining multiple hybrid control strategies, this paper proposes a multi-priority dual-clock probability detection CSMA(MPDCPD-CSMA) protocol with a monitoring mechanism. The field-programmable gate array (FPGA) hardware circuit is used as an experimental research platform for the first time. Cognitive wireless network MAC protocol design and implementation. The design took full advantage of the flexibility of the FPGA, using a hardware description language Verilog HDL and schematic input combined with the QuartusII9.0 circuit design. By comparing the statistical values of the circuit system with the theoretical values, it is verified that the design has the characteristics of good real-time performance, high reliability, and strong portability. It can effectively reduce system node energy consumption, improve system throughput, and can be applied to wireless networks.<\/jats:p>","DOI":"10.3233\/jifs-169678","type":"journal-article","created":{"date-parts":[[2018,6,15]],"date-time":"2018-06-15T13:21:12Z","timestamp":1529068872000},"page":"1353-1361","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["FPGA-based research of monitoring MPDCPD-CSMA protocol in cognitive wireless networks"],"prefix":"10.1177","volume":"35","author":[{"given":"Zhi","family":"Xu","sequence":"first","affiliation":[{"name":"School of Information, Yunnan University, Kunming, China"}]},{"given":"Hongwei","family":"Ding","sequence":"additional","affiliation":[{"name":"School of Information, Yunnan University, Kunming, China"}]},{"given":"Qianlin","family":"Liu","sequence":"additional","affiliation":[{"name":"Yunnan Military Command Region, Kunming, Yunnan, China"}]},{"given":"Zhijun","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Information, Yunnan University, Kunming, China"}]},{"given":"Liyong","family":"Bao","sequence":"additional","affiliation":[{"name":"School of Information, Yunnan University, Kunming, China"}]},{"given":"Gang","family":"Zhan","sequence":"additional","affiliation":[{"name":"School of Information, Yunnan University, Kunming, China"}]}],"member":"179","published-online":{"date-parts":[[2018,6,14]]},"reference":[{"issue":"4","key":"e_1_3_2_2_2","first-page":"723406","article-title":"Proposal of dynamic subcarrier selectiontechnique using CSMA\/CA for cognitive wireless mesh networks[J]","volume":"7234","author":"Brownlie D.","year":"2009","unstructured":"BrownlieD. and SarenM., Proposal of dynamic subcarrier selectiontechnique using CSMA\/CA for cognitive wireless mesh networks[J], Proc Spie7234(4) (2009), 723406\u2013723411.","journal-title":"Proc Spie"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1166\/sl.2015.3456"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.14257\/ijfgcn.2015.8.5.12"},{"key":"e_1_3_2_5_2","doi-asserted-by":"crossref","unstructured":"ZhanG.
